Abstract
A method for operating a LiDAR system in an automobile that can include receiving noise data corresponding to an ambient noise level, receiving false positive data corresponding to a rate of false positive object detection occurrences; determining an object detection range spanning a distance defined by a minimum range of object detection and a maximum range of object detection for the LiDAR system; generating an object detection threshold value for detecting objects based on the noise data and the rate of false positive data; applying the object detection threshold value to each of a plurality of range values within the object detection range; and applying a gain sensitivity profile to the object detection threshold value at each of a plurality of range values.
